On 18 April 1948, the enemy approximately 250 strong, supported by 3-inch mortar, MMGs and LMGs made persistent attacks on a picquet vital for the defence of Uri. The main attack came from the south on a platoon which was commanded by Jemadar Sanwal Ram. With complete disregard for his personal. safety, Jemadar Sanwal Ram went from post to post in pitch darkness encouraging his men and at the same time hurling grenades at the enemy. The enemy, having failed to over-run the position in three waves, made a final desperate attempt to rush in. At this moment, Jemadar Sanwal Ram went forward under incessant enemy fire and killed five enemy soldiers with his sten gun and grenade. After five hours of grim fighting, dawn found several enemy dead lying in front of Jemadar Sanwal Ram's post. Throughout the action, this JCO acted with coolness and daring of the highest order.
